Chapter 20 - Stop Ansible Failures! Learn Block,Rescue & Always with 5 Real‑World Labs (AutomateOps)

Welcome back to Welcome back to AutomateOps! In this session, we break down one of Ansible’s most powerful automation patterns: Block → Rescue → Always — the secret weapon behind reliable, fault‑tolerant playbooks. You’ll not only understand the theory behind each component, but also practice 5 real-world hands‑on labs that demonstrate how to: Handle unexpected task failures Implement OS‑specific fallback logic Create self‑healing configurations Recover from missing services automatically Trigger logical failures using facts Summarize partial failures gracefully In this session, we break down one of Ansible’s most powerful automation patterns: Block → Rescue → Always — the secret weapon behind reliable, fault‑tolerant playbooks. You’ll not only understand the theory behind each component, but also practice 5 real-world hands‑on labs that demonstrate how to: Handle unexpected task failures Implement OS‑specific fallback logic Create self‑healing configurations Recover from missing services automatically Trigger logical failures using facts Summarize partial failures gracefully 🔥 What You’ll Learn in This Video 📘 Theory (from the PPT) How block groups tasks and controls flow Why rescue is essential for error‑handling and fallback How always guarantees logs, cleanup, and notifications Failure semantics (rc != 0, failed_when, ignore_errors) Best practices for writing reliable playbooks Youtube chapters: 00:00 Introduction 00:39 Theory: Block, Rescue & Always 02:31 Lab Setup: AWS EC2 + Dynamic Inventory 04:21 Lab 1 – Intentional Failure → Rescue → Logging 07:41 Lab 2 – Missing Directory → Create → Retry → Verify 11:56 Lab 3 – Chrome Service Fail → Install → Start → Summary 15:01 Lab 4 – Disk Space Threshold Logic → Telemetry 17:41 Lab 5 – Package Install Failures → Summary Reporting 20:31 Final Summary & Closing Remarks 🧪 LAB (from the attached playbooks) 1️⃣ Simulate a task failure → trigger rescue → write logs in always 2️⃣ Correct missing directories during file copy using rescue 3️⃣ Restart cron → reinstall if missing → show final service status 4️⃣ Use structured facts to detect low disk and trigger logical failures 5️⃣ Handle partial failures in loops and summarize results 🎯 Who Should Watch This Video?
